HARROW.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed March 21, 1904:. Serial No. 199.078.

To a/ZZ whom it may concern.'

Be it known that I, FEDER LAURSEN, a citizen of the United. States, anda resident of Racine, in the county of Racine and State of Wisconsin,have invented certain new and useful Improvements in Harrows; and I dohereby declare that the following is a full, clear, and exactdescription thereof.

My invention has relation to improvements in harrows; and the inventionconsists in the construction and arrangement of parts as will behereinafter described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a view in side elevation,partly broken away to illustrate certain details of construction. Fig. 2is a detail plan view, partly in section, on the plane indicated by line2 2 in Fig. 1. Fig. 3 is a detail vertical sectional view taken on theplane indicated by line 3 3 in Fig. 1.

Referring to the drawings by reference-numerals, 1 1 designate parallelside bars, and 2 2 parallel end bars, which are united to provide aframe.

Numeral 3 is a ring or loop secured to one of the end bars for theattachment of the necessary draft device.

Cn the und-er surfaces of the side bars 1 1 are journal-boxes 4 4,adapted to receive the studs 5 of the shafts 6. Suitably fastened toeach of the shafts 6 are a plurality of harrowteeth 7, having their endscurved all in the Said harrow-teeth are arranged in pairs and disposedat various angles about the shafts, such disposition permitting theteeth of one shaft to revolve between those on the adjacent shaft.

A second frame or housing that serves in the capacity of a platform isdesigned to rest on the lower frame. Said platform comprises side bars 99, arranged above and parallel with the side bars 1 1 of the lowerframe, and end bars 8 8, designed to be supported by the end bars 2 2 ofthe lower frame.

Numerals 10 10 designate corner-posts secured to the upper frame anddepending down against the inner corners of the lower frame to preventlateral movement of the upper frame.

The upper frame is provided with transverse spaced-apart slats 11,secured to the top surfaces of the longitudinal bars 9, and these slatsserve as beaters in crushing or breaking the clods of earth as they arethrown upward by the interposing teeth, whereby said clods of earth arepermitted to strike against the lower side edges of said slats. Theseslats also sup port a longitudinal beam 12, which is secured midway ofsaid slats and on which is secured a drivers seat 14, mount ed on aspring-support 13, secured to said beam by a bolt 15.

When the harrow is operated in the direction shown in Fig. 1, clods ofearth, cornstalks, and the like will be picked up and operated upon bythe rearwardly-projecting portions of the teeth of one roller and theforwardly-projecting teeth of the next following roller. When the pullof the harrow is reversed, the curved portions of the teeth will have achopping effect upon the soil, and

thereby pulverize the same, the direction of Y* the pull of the harrowdepending upon the condition of the soil. For this latter operation Ireverse the position of the drivers seat by turning the spring-post 13about the bolt 15. if'

From the foregoing description, taken in connection with theaccompanying drawings, the construction and mode of operation of theinvention will be understood without a further extended description.

Changes in the form, proportions, and minor details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described the invention, what I claim is- A harrowconstructed of longitudinal side bars and transverse end bars securedtogether to constitute a lower frame having a plurality of shaftsjournaled in its side bars arranged one in front of the other, each ofsaid shafts having harrow-teeth thereon, a flat upper frame having sidebars parallel with the side bars of the lower frame and supported by theend bars thereof, said end bars serving to space apart said upper and.lower frames, means depending from the up- IOO per frame and contactingWith the lower i have hereunto set my hand at Racine, inthe frame toprevent lateral movement of the county of Racine and State of Wisconsin,in upper frame 'and said upper frame having the presence of tWoWitnesses.
